playground: go generate fails when GOROOT is user-writeable. #69
Description
Following gopherjs/gopherjs#787 I'm seeing the playground fail to regenerate:
cd `mktemp -d`
export GOPATH=$PWD
go get github.com/gopherjs/gopherjs
go get github.com/gopherjs/gopherjs.github.io/playground
export PATH=$PWD/bin:$PATH
cd src/github.com/gopherjs/gopherjs.github.io/playground
gopherjs --version
go generate
with:
cp: cannot stat '/tmp/gopherjs_playground.QXOsmkSXHw/gopath/pkg/*_js_min/github.com/gopherjs/gopherjs/js.a': No such file or directory
This is, I believe, because js and nosync are fully vendored.
@shurcooL - what do you think is going on here?
